Application filed June 6,

and effective means in "which water may be raised from a base at a continuous flow to any desired elevation.

A further object is to produce a means for elevating water or similar fluids in which a i casing has its bottom provided with an opening whose passage is controlled by an inwardly opening valve and which is designed to-rest in a: supply of water,such as a cistern, said casing having passing therethrough a l fluid outlet pipe which is provided, with a ball valve for closing the bottom thereof but which valve is designed tobe opened by the pressureof water from the cistern so that the water inthe casing and in the pipe will be substantially level with that in the cistern, while weight; influenced means is provided for operating valves to permit air under pressure entering the casing to eject water through the outlet pipe therefor when a determined quantity of water has entered the casing, and upon the fall of the water to close the air inlet and to open the air outlet to permit an additional supply of water from the casing and the outlet pipe, such operation being. continuous as long as the water is being elevated from the cistern.

The foregoing, and other objects which will present themselves as the nature of the invention: is betterunderstood, may be accomplishe'd, by aconstruc'tion, combination and operative association of parts such as is disclosed by the drawings which accompany and which-form part of this application.

In the draw1ngs:- I Figure l is ageneral view of the improvement arranged 1n a cistern or other source from which water is to be elevated,

the wall of the cistern being in section.

' Figure 2 is an enlarged approximately central'v-ertical longitudinal sectional view 1922. Serial No. 566,372.

sources, I have, for the purpose of illustration,shown in the accompanying drawings, the same arranged in an ordinary cistern, the said cistern being indicated in the said drawin s by the letter C.

In carrying out my invention, I make use of a'preferably cylindrical casing 1. The casing 1 is open at both of its ends, but the said'ends are closed by castings. The top casting indicated by the numeral 2, has its flat under face provided with an annular groove 3-, in which there is preferably ar-' ranged a gasket, and in the groove 3 the upper end of the casing 1 is received. The bottom casting 4 has its upper fiat face like- Wise provided with an annular groove 5 1n which is seated a gasket. The under face of the bottom casting 4: is provided with ribs or legs 6 which elevate the bottom of the casting above the bottom of the cistern 1.

Passing through suitable aligning openings in the castings which provide the top and bottom plates of the cylinder there are bolts 7, suitable nuts 8 being screwed on the bolts for forcing the ends of the casing into the grooves 8 and 5 and in tight contact with the washers in the said grooves. The bottom' l of the cylinder is centrally provided with a round opening 9, and screwed in this opening there is a seat 10 for a weighted valve 11, the valve opening inwardly of the casing.

Screwed in the seat 10 there is a T, and screwed in the ends of the T are pipes having couplings on their ends provided with short pipes. In this'manner the water front I nates a suitable distance above-the bottom- 4:

of the casing, the lower end of the said tube being provided with a valve seat 13 for an inwardly opening spherical valve 14-. Also V tively. In the bore of theport 17, at the portion thereof which communicates with the casing 1 there is secured a valve seat 20 for a ball valve 21. The port 16 provides an air inlet port, and communicating with the said port 16 there is an air conducting pipe 22. i

The top 2, adjacent its opposite end is provided with a straight port or passage 23 which has in'its lower wall a valve seat 24; for a ball valve 25. The valves 21 and 25 are provided with stems 26 and 27 respectively. The stem 26 extends into the casing 1, the stem 27, for the valve 25 extending both in the casing 1 and. through a guide-in the port or passage 23. The stems 26 and 27 have their inner ends loosely received in sleeves 28. A pin 26 passes through the valve stem and slots 28 in the sleeves. The sleeves. are interiorly threaded and are screwed on the parallel arms 29' of asub nection of the arms 29 withthevalve stems stantially U-shaped frame. The lower or connecting member of the frame isindicated by the numeral 30. This member SO is centrally provided with a ring flange 31 that surrounds the tube 12. The members 29 of the frame are connected by a brace 32, disposed only a slight distancefrom thecon- 26 and 27 .7 The frame is preferably in the nature of a rod member, as is the brace 82, the said brace being centrally formed with a ring portion 33 that surrounds the tube 12. Arranged for free movement, around the tube 12 between the bottom 30 of the frame and the brace 32there is afloat 3 1. I Air or other fluid under pressure is con-.

7 (not shown) ducted through the pipe 22, and the, saidine has its oassa e controlled b a valve The arms 29 of thelframe have prefera ably screwedthereon nuts 36 whichare in contact with the'sleeve members 28, so that the frame may be effectively held adjusted on the valve stems 26 and 27.

1 ()n the brace 32 there isan upwardly directed arm havin an an le end or fin er 36'. be c Th sfinger is movable between two weight ed members 37 which are pivotallyisupported. at 38 to theunder face ofthe casting 2.

The weighted members havetheir confront-. H

.ing faces notched at spaced intervals.

The operation may be briefly described as, follows: W r We will suppose that the .airinlet, control valve 21 is seated and the airfoutlet control valve 25 is unseated. Water from the cistern will flow into the casing through the opening 9,-unseatingthe weighted valve 11, and such water will likewise enter the tube 12.

The water in the casing will elevate the float 34;, and when the samerises sufficiently,

' it will contact with the brace 32, and in so doing will raise the frame 29 tofopen the air inlet, valve 21- and close the air outlet valve 25. Air will now enter the casing through the passages-16 and 17 and exert pressure on the water in the casing, will force I such water through the pipes 12 and15 and will also, of course, close the .valve 11. The finger 36 is now engaged in the aligning notches in the pivoted weights 87 and will tend to hold the frame elevated and the Y valve 20 insulated until all of the water in the casing is displaced; The frame will then by its own weight, descend and cause the seating of the valve 21 and'the unseat-: ing of-the valve 25. The air. now finds an outlet through the open valve. seat 2 1 and the port 28, allowing thepressure ofthe water in the cistern to again unseat the valve 11 and enter the casing. The ope-ration is I continuous as long as water enters the casing 1, and air is likewise permitted-to enter the casing. 7

. It is thought that the foregoing description, when taken .injconnection with the drawings will fully set forth the construe-i tion,foperationand advantages of the ims provement" to those skilled inthe :art'sto which this invention relates,,and therefore further detailed description will not be athowever, that the description and. illustration refer only: to a satisfactory embodiment tempted. It isthought necessary toz add,

of the improvement asit now appears tome and that Iain e'ntitledztoall such changes therefrom as fall withinflthe scope ofwhat ii I. claim. j 1 r ;v
